Proposed high-rise building fire hydrant control valve using signal valve discussion
Abstract: High-rise building fire hydrant control valve signal valve to explore Keywords: high-rise building hydrant control valve signal valve in accordance with the "high-rise civil building fire code" requirement, in the indoor fire hydrant system, the water supply pipe valve is divided into several independent sections, And the valve should have a clear sign of opening and closing. This is so that there should be not less than one fire hydrant standpipe to be stopped when servicing the pipeline. With the development of modern architecture, all kinds of ducts in the building should be concealed as beautiful as possible. Therefore, it is ubiquitous to dispose the hydrant pipes inside the ceiling and in the well. However, there is a problem that the control of the hydrant pipes The valve is not open to monitor the status of the fire hydrant to the normal use of the potential hazard. For example: "Power Grid National Grid Control Center" project for the construction area of ​​50,000 square meters, three underground, 27 floors above the building height of more than 110 meters for the production command scheduling, office meetings and other functions One of the integrated intelligent building, the high degree of automation in China is rare. In its automatic spray system design, I will use all the water flow indicator valve are used in the valve, so the state of the system can be displayed in the fire control center, and can be clearly identified the problem, while living and fire water level Control, fire pump start and stop, etc. have also been a reasonable monitoring, except the fire hydrant system control valve in accordance with the specification only ordinary valve, it has obvious signs of opening and closing, but not in the fire control center display, the other These valves need to be located in the tube well and ceiling for aesthetic purposes. At present, the quality of workers can not guarantee the reliability of the system. Therefore, during the inspection and acceptance of its fire-fighting system, although leaders of the Ministry of Electric Power Engineering Command, construction units and design institutes attached great importance to the deployment and rectification as early as possible and rehearsed well, during the formal actual inspection of the fire station, There was a problem, there is a fire hydrant standpipe fire hydrant in any case put no water, while the other four are normal water, fire control center also found no problem. After the inspection found that this root riser closed because of overhaul at both ends of the control valve, and the overhaul of workers did not open the valve, resulting in hydrants do not water. In my opinion, such a problem still arises under the circumstances that everyone attaches great importance to. However, it is even more troubling to find out what kind of problems we usually face when it is easy to paralyze. This is a key issue that relates to whether the fire hydrant system can be used reasonably in a fire. The most reliable way to avoid this is to set the control valves of the fire hydrant system as signal valves, and the valve open state can be used in the fire control The center shows it for managers to test, and although the costs have risen, its investment in the entire hydrant system is still minimal, and it can make the entire hydrant system much more secure, which I think is worth the investment .
